Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604102, here are decompositions:

3 + 31604099 = 31604102
223 + 31603879 = 31604102
421 + 31603681 = 31604102
613 + 31603489 = 31604102
709 + 31603393 = 31604102
853 + 31603249 = 31604102
991 + 31603111 = 31604102
1093 + 31603009 = 31604102

Showing the first eight; more decompositions exist.
